KQ2VGA adds almost a whole half a game into the original.
More like changes the originally completely... Turns the original upside down...
playing a sick game (Breast Intentions). It just sounds like something made by a perv, a pointless game.
I have played it, its actually pretty kosher and tame, its basically not much more than KQ3 done in reverse, with elements of KQ1 tossed in... It's more silly than anything. Not perverted, and its not 'sick'. There are no sexual elements in the game at all.
This is the about the most graphic nudity you will find in the game (Valanice has just given birth, and the twins are feeding for the first time, and you can still see their umbilical cords);

QFG2 had more voyarism with the X-Ray specs, ;).
KQ2 had far more questionable hidden easter eggs material in the files, and don't forget the sexual scenes in KQ8, the nudity and the dildo.
Mod Warning: partial nudity

If you want to avoid a perverted fan game, avoid Quest for Glory 4 1/2, or many of the official Leisure Suit Larry games.
One of the scenes in QFG4 1/2 (involves a scene of sexual nature between the Hero and Hilde the Centauress)
